DQ500 Overhaul Kit, new and ready to install. Fits the DQ500. Ships fast from the USA.
The DQ500 is the heavy-duty seven-speed DSG that VW and Audi fit where the smaller gearboxes run out of torque: the Transporter, high-output Tiguan and Passat diesels, and the Audi TT RS. When one of these starts leaking, loses pressure on a clutch circuit, or comes out for a clutch or mechatronic repair, this DQ500 overhaul kit replaces the rubber and gasket side of the job. It is a new aftermarket seal and gasket kit for the 0BH and 0BT gearboxes, and it includes the valve body sleeves and pistons that wear and leak inside the hydraulic unit.
Like the DQ250, the DQ500 uses two wet multi-plate clutches, one for the odd gears and one for the even gears, applied by oil pressure from the mechatronic. Volkswagen built it for up to 600 Nm, so the clutches need high, accurately controlled pressure to hold. Every seal along that path matters. Hardened O-rings, worn valve sleeves or a leaking cover gasket let pressure bleed away, and the control unit raises the command to compensate until it runs out of adaptation range or sets a pressure fault. The kit shown in the photos includes a large perimeter gasket, a metal-carrier gasket plate, eight steel sleeves with O-rings, filter screens, shaft seals and an assortment of O-rings and sealing rings. Lay it out against the parts you remove before you start, because the instructions are not included.
Scan the transmission module and note every stored code. Ross-Tech lists the fluid pressure sensor fault 17225/P0841 with causes ranging from wiring to the mechatronic and valve body, which is exactly where these seals live. Then road-test while logging commanded versus actual clutch pressure. A circuit that falls away from command as the fluid warms is the classic leak pattern. Our DSG pressure testing guide covers reading those values, and the DSG overheating guide explains how heat hardens seals and degrades fluid.
This kit is for the DQ500 seven-speed DSG, VW parts prefix 0BH or 0BT. Volkswagen launched the DQ500 in September 2009 in the Transporter T5 2.0 TDI, then used it in the Tiguan 2.0 TDI 4Motion, BiTDI Passat and Tiguan, and from 2010 in the Audi TT RS as a seven-speed S tronic. In North America it is a less common gearbox, and many VW and Audi models sold with a seven-speed DSG use the dry-clutch DQ200 or the 0B5 instead, which this kit does not fit. Read the gearbox code from the vehicle data label or the case and confirm it starts with 0BH or 0BT. If you are not sure, send us your year and VIN before ordering. For a dated DQ500 version, see our DQ500 overhaul kit 2014, and for every part we carry for this family, visit the DSG and S tronic collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is a seal, gasket, sleeve and piston kit. Friction and steel plates are sold separately, and they should be replaced too if the clutches are worn.
Only if that gearbox is a DQ500 (0BH or 0BT). Many seven-speed DSGs in smaller VWs are the dry-clutch DQ200 (0AM), which uses completely different parts. Check the code before ordering.
No. The kit does not include instructions, so work from factory repair information and match each seal to the part you remove.
Fill with the correct DSG fluid, then run the DQ500 basic settings with a capable scan tool. Fluid must be above 15 C, both brakes held, lever in Park, engine idling. If the mechatronic was replaced, transfer the coding.
Yes. An internal leak lowers actual pressure compared with what the module commands, and that can lead to pressure or clutch adaptation faults. Wiring and sensor faults can set similar codes, so diagnose first.
